Preparation method of low-cost ultra-large and ultra-thick carbon/carbon composite material
The invention provides a preparation method of a low-cost ultra-large and ultra-thick carbon/carbon composite material. The preparation method comprises the following steps: a, preparing a carbon fiber preform; b, carrying out graphitization treatment on the carbon fiber preform to obtain a carbon fiber blank; c, sequentially carrying out dipping curing treatment, carbonization treatment, high-temperature heat treatment and machining treatment on the carbon fiber blank; d, repeating the step c until the density of the carbon fiber green body reaches a target value to obtain a primary finished product; and e, carrying out finish machining on the primary finished product to obtain a finished product. The method is simple in process and low in production cost, the prepared product is high in percent of pass, the production cost is low, and low-cost batch preparation of the ultra-large and ultra-thick carbon/carbon composite material can be achieved.
本申请提供一种低成本超大超厚碳/碳复合材料的制备方法，包括以下步骤：a.准备碳纤维预制体；b.对碳纤维预制体进行石墨化处理，得到碳纤维坯体；c.对碳纤维坯体依次进行浸渍固化处理，炭化处理，高温热处理，机械加工处理；d.重复所述步骤c，直至碳纤维坯体的密度达到目标值，得到初成品；e.对初成品进行精加工，得到成品。该方法工艺简单，生产成本低，制备出的产品合格率高，生产低成本，能够实现超大超厚碳/碳复合材料的低成本批量制备。
